  • Magnetic bubble memory bias magnet arrangement
    Patent number: 4027298
    Abstract: An in-plane magnetic holding field, long known to provide improved operating margins for a magnetic bubble memory during stop-start operation, is produced by a unique bias magnet design which provides a constant in-plane bias field in a manner consistent with normal bubble propagation as well as with stop-start operation.

  • Single-wall domain arrangement
    Patent number: RE29677
    Abstract: The transfer of a domain from one channel to another in a single-wall domain memory is effected by a transfer loop into which a domain is moved by a field from a pulsed conductor and from which a domain exits in response to a magnetic field rotating in the plane of the layer in which domains move. The transfer loop includes two "exit-entrance" positions associated with the two channels between which transfer occurs. The exit of a domain from the transfer loop may be aided by a pulsed conductor also.
